12) we find the reading [Greek: aeto de humon to nai nai, kai to ou ou], and that in the Clementine Homilies twice over we read [Greek: esto humon to nai nai, (kai) to ou ou], [Greek: kai] being inserted in one instance and not in the other.

Justin's reading is found also exactly in Clement of Alexandria, and a similar reading (though with the [Greek: aeto] of James) in Epiphanius.

These last two examples show that the misquotation was an easy one to fall into, because there can be little doubt that Clement and Epiphanius supposed themselves to be quoting the canonical text.

There remains however the fact that the Justinian form is supported by the pseudo-Clementines; and at the first blush it might seem that 'Let your yea be yea' (stand to your word) made better, at least a complete and more obvious, sense than 'Let your conversation be' (let it not go beyond) 'Yea yea' &c [Endnote 122:1].

There is, however, what seems to be a decisive proof that the original form both of Justin's and the Clementine quotation is that which is given in the first Gospel.
